Note

Medium Risk
Modifies request URL construction in _build_request to merge URL-embedded query params with user/default params, which could subtly change behavior for any endpoint paths containing ?. The change is covered by new sync/async tests, but it touches core client request building.

Overview
Releases 0.48.0 (version bumps in pyproject.toml, _version.py, release metadata, and changelog).

API surface change: adds optional base_url to multiple browser session response models (BrowserCreateResponse, BrowserRetrieveResponse, BrowserUpdateResponse, BrowserListResponse, BrowserPoolAcquireResponse, and InvocationListBrowsersResponse.Browser).

Client behavior fix: updates _base_client.py so hard-coded query params present in options.url (e.g. "/foo?beta=true") are preserved and merged with caller/default params; adds sync and async tests to lock in the expected merged query behavior, including percent-encoded paths.
